A group read bearing steel, collection - bearing knowledge

Bearing steel is used in the manufacture of rolling bearings of rolling body and inner and outer ring of steel, usually used in the condition of quenching. Rolling bearing in the work to carry high alternating load, the contact stress between roller and inner and outer ring, and also work in lubricant medium. Therefore, rolling bearing steel with high compressive strength and the fatigue strength, has a certain toughness, plastic, wear resistance and corrosion resistance, the internal organization of steel composition is uniform, heat treatment has good dimensional stability.
